According to actual need for Shenyang fire fighting command and communication system, the optimum path from fire fighting team station to fire site was solved in GIS environment.
本文从沈阳市消防通信指挥系统的实际需要出发,在GIS环境下求解从消防中队到火灾发生地的最佳路径。
Using the optimum code can obtain the optimization of communication system. Different system optimization targets can produce different optimum code.
通信系统的优化可用最优编码方式实现,不同的系统优化指标可产生不同的最佳编、译码方式。
But, it may be not a optimum system using an "AD hoc" method to combine the optimum source with channel coders in practical communication systems.
但是,在实际中发现,用某种“特定”方法连接起来的最优信源编码器和信道编码器,并不一定能构成最佳通信系统。
